beta-glucosidase — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0117660 (beta-glucosidase) on barley chromosome 2H encodes a glycoside hydrolase family 1 protein with DIMBOA-glucoside beta-D-glucosidase, ABA-GE beta-glucosidase, and numerous other beta-glucosidase activities. The gene is associated with abscisic acid metabolism, coumarin metabolism, indole glucosinolate anabolism, and defense responses including callose deposition, response to insects, and induced systemic resistance. It is linked to ER body organization, protein polymerization, and cellular responses to cold, salinity, chitin, and bacterial molecules. The product localizes to the ER body, ER lumen, apoplast, vacuole, plasmodesma, and extracellular space. Associations include seed weight, water use efficiency, bacterial blight disease resistance, anthocyanin content, oxidative stress response, stomatal complex closure time, and leaf, root, and floral development traits. Studies of related genes in other species link the family to drought response, abscisic acid hydrolysis, germination timing, and herbivory resistance.
